Centner INTRODUCTION In today's world, millions of people lack access to sufficient quantities of food to meet recommended dietary needs.1 As the world's population grows, global demand only increases for food and fiber.2 These shortages are occurring despite significant increases in the production of food resulting from new and modified practices in- cluding the more intense use of land resources, irrigation, plant breeding,5 genetically modified crops,6 advances in technology, im- Copyright C 2014 Terence J. Centner. I Terence J. Centner is Professor of Agricultural and Applied Economics at the University of Georgia and his teaching program involves environmental, public health, and agribusiness law courses. He focuses on policy analyses of current issues confronting agriculture and the environment. 1. It is estimated that one in seven people lack access to sufficient protein and energy in their diet. Charles J. Godfray et al., Food Security: The Challenge ofFeeding 9 Billion People, 327 ScI. 812, 812 (2010). 2. It is estimated that by 2050 the world will need 70 percent more food due to increasing popula- tion and changes in diets. J6zsef Popp, Karoly Peto & Janos Nagy, Pesticide Productivity and Food Se- curity: A Review, 33 AGRONOMY SUSTAINABLE DEv. 243, 243 (2013). Population growth is also ac- companied by an increase in the demand for water for the production of food crops. Henry Vaux Jr., Water for Agriculture and the Environment: The Ultimate Trade-off 14 WATER POLY 136, 137 (2012). Due to insufficient irrigation water, millions of people will be condemned to starvation. Id. 3. See Uwe A. Schneider et al., Impacts ofPopulation Growth, Economic Development, and Tech- nical Change on Global Food Production and Consumption, 104 AGRIC. SYS. 204, 205 (2011) (noting that intensification of water, fertilizer, pesticides, machinery, and labor has increased food production). 4. See David Molden et al., Improving Agricultural Water Productivity: Between Optimism and Caution, 97 AGRIC. WATER MGMT. 528, 530 (2010) (observing potential crop production gains from irrigated crops by reducing plant transpiration). 5. See Godfray et al., supra note 1, at 813 (noting the Green Revolution using plant breeding to in- crease crop production); Eyal Fridman & Dani Zamir, Next-generation Education in Crop Genetics, 16 CURRENT OP. PLANT BIO. 218, 219 (2012) (reporting on the dramatic increases in yields due to hybrids); Mark Tester & Peter Langridge, Breeding Technologies to Increase Crop Production in a Changing World, 327 SCI. 818, 818 (20 10) (calculating a linear increase in food production globally of 32 million metric tons per year due to breeding and agronomic improvements). 6. Genetically modified crops can decrease losses from pests and increase yields by eliminating competition from weeds. See Parvaiz Ahmad et al., Role of Transgenic Plants in Agriculture and Bio- pharming, 30 BIOTECH. ADVANCES 524, 525 (2012) (identifying wheat, rice, and soybean as important transgenic crops that have increased food supplies). 7. Technologies enable agricultural production to be intensified through the employment of more water, fertilizer, pesticides, and machinery. Schneider et al., supra note 3, at 205. 1
